My invention pertains to shipping containers and has among its objectsto produce a container made from fibre board or similar material that ischeap and easy to manufacture, is strong and durable yet light inweight, and is waterproof which adapts it for use in over-seas shippingand for packaging articles that must be protected against atmosphericconditions and changes.

A principal object of my invention is to provide means whereby allengaging surfaces constituting the container closures are drawn and heldinto highly compressedrelationship to eil'ect water repellent seams.

The square corners or edges make it easier to obtain a tight sealwith The above and other objects and advantages are attained by myinvention, one embodiment of which I have illustrated in theaccompanying drawings.

Fig. 1 is a plan view of one end of a blank from which the body or shellof the container may be formed.

Fig. 2 is an exploded view, in perspective, showing one end of the bodyand the three-piece head or end closure.

Fig. 3 is a front elevation, partly broken away, of a preferred form ofthe container.

Fig. 4 is a similar view of a modified form.

Fig. 5 is a perspective view of one end of a modified form of body orshell.

Fig. 6 shows a single-piece cover adapted to be used in a modified formof head or end closure.

Fig. 1 shows one end of a'single-piece blank from which the shell orbody of the container of Fig. 3 is fabricated. Only one end of the blankthe heads or end closures. However, thereare many rposes that can beserved by rule-scoring the ntire blank when using such material as Vboard.

when the container body is to be formed as shown in the lower part ofFig. 2, the edge M which forms an outside or exposed edge in thecontainer is coated with a water-repellent compound and the outersurface of panel I4 is coated with a water-repellent adhesive such aswellknown waterproof glues, or other water repellent adhesives. Theblank is next folded on the score lines and the panel l0 pressed firmlyagainst the waterproof tape 22.-

is shown, because the two ends are identical.

The blank comprises five panels or sides H), II, l2, l3, lldeflned byscore lines l5, l6, l1, l8, along whichthe material is folded to formthe container'body. The width of the panels equals the width of therespective sides of the container that they are to form, except thatpanel Ill,

which overlaps panel It so as to provide a side of double thickness, maybe of suflicient width to overlap panel 14 only far enough to securea'flrm bond or joint therewith, as shown for example in Fig. 5. Thescore lines l5, l6, l1, It, will vary according to the material beingused and the character ofthe-container to he made". vWhen laminatedwaterproof board, such for example as ,Government specification V-2-S,or equivalent,

is used, a complete score without cuts is preferable, but withother'board materials I prefer to make the line l5 a'cut-score and thelines I8, I1,

adhesive coated side of panel H until ,a secure bond is obtained.Stitching or stapling can also be applied to strengthen the bond. Thecomer where some of the fibers are exposed by the cutscore l5 may beprotected and reinforced by a The heads or end closures Y preferably areformed from three parts, as shown in Fig.2. The inner seal is made fromtwo covers 23, 24 each of which has a flat panel adapted to flt snuglywithin an end of the shell, and two sets of flanges fitting over andsecured to the inside and outside of the top of the shell. 'The grainofthe board should run at right angles in the respective covers and theentire covers may be dipped in water repellent materials such asasphaltum especially compounded to avoid brittleness at lowtemperatures, waxes and other suitable mate- The inner cover23 has aflat panel which has 2 a snug fit within the four walls of the shell andrule-scores except for a short distance at each end where they arecut-scored as at I9, 20, 2|. The cut-scores It, l9,'2ll, 2|, enable thematerial at two opposite sides has inner or upturned flanges 25, 26,which are sealedto the inside-of two opposite panels, as l2, l4,- andlimit the depth to which the cover enters the shell. Outer or downturnedflanges 21,28 are secured to the out- I side of the panels l0, l2.

The outer cover 24 has a flat panel with its edges fitting snuglyagainst the flanges 25, 26 and has upturned flanges 29, 30, adapted tobe sealed to the inside of the side walls. ll, 13.
